TOBACCO-PIPE.

Application filed June 11, 1914.

To all whom it may concern:

Be it known that I, WALTER T. Ross, a citizen of the Dominion of Canada, residing at Vancouver, in the Province of British Columbia, Canada, have invented certain new and useful Improvements in Tobacco- Pipes, of which the following is a specification.

This invention relates to a tobacco pipe which has been particularly designed to maintain the bowl and the duct through which the smoke passes to the mouthpiece free from moisture and unobstructed by accumulation of nicotin, etc., which drain to a removable receptacle provided at the lower end of the pipe shank or stem. The ducts are also particularly arranged to be readily accessible for cleansing by a direct pull through.

The invention is fully described in the following specification, reference being made to the drawings by which it is accompanied, in which:

Figure 1 is a vertical longitudinal section through the axis of the pipe and its ducts. Fig. 2 is a cross section of the stem of the pipe on the line A in Fig. 1. Fig. 3, a similar cross section showing a modification, and Fig. 4, a longitudinal section of the stem showing a modified construction of the bushing.

In these drawings 2 represents the bowl of the pipe and 3 the stem, the axis of which stem is at an acute angle to that of the bowl and is at the lower end produced beyond the axis of the bowl and provided with a removable receptacle 10. A bent mouthpiece 4: is removably socketed in the upper end of the stem.

In the preferred form, the shank 3 is axi ally bored to receive a bushing 5 of any suitable material, which may be shorter than the stem to permit the mouthpiece to socket therein. This bushing 5 has upper and lower lengthwise ducts 6 and 7 which extend straight through parallel to the axis of the bushing. At the lower end these ducts 6 and 7 deliver into the receptacle 10 and at the upper end communicate with the duct 12 of the mouthpiece which is enlarged at 11 to include them both. The duct 8 from the bottom of the bowl 2 is drilled straight through in substantial alinement with the axis thereof, to intersect both the ducts 6 Specification of Letters Patent.

and 7 of the stem and to deliver into the receptacle 10.

In a pipe so constructed the smoke is drawn directly through the duct 8 from the bottom 01 the bowl and through the upper or smoke duct 6 of the stem to the duct 12 of the mouthpiece. Any moisture draining from the tobacco in the bowl'has thus a downward tendency direct to the receptacle 10, and any that may condense in the smoke duct 6 will also drain downward. Such of the moisture as may be drawn along the smoke duct 6 will, on escaping from the upper end of the duct, drain back to the receptacle 10 through the lower duct 7 as also will any moisture condensing from the breath in the duct 11 12 of the mouthpiece, the enlargement 1.1 of which affords a considerable area on which it may condense and running down the sides will deliver into the lower or drainage duct 7 The mouthpiece 4: and receptacle 10 being removed may be independently cleaned, and the ducts 6, 7 and S of the pipe being straight and open at both ends can have a cleaner passed straight through them and can be easily inspected for obstruction.

The ducts 6 and 7 may be drilled in the body of the stem, as shown in Fig. 3 of the drawing, but the bushing 5 is the preferred construction, and the end of that bushing externally threaded, as shown in Fig. t, forms a satisfactory means of connecting the receptacle 10 to the lower ends of the three ducts 6, 7 and S.

The smoke of this pipe is always cool and dry as it is drawn through the upper duct of the stem and does not come in contact with the moisture which drains down the lower duct.

Having now particularly described the invention, I hereby declare that what I claim as new and desire to be protected in by Letters Patent, is:

1. A tobacco pipe the stem of which is produced beyond thebowl and has an upper and a lower duct parallel to the axis of the stem said ducts connected to one another by a duct in axial alinement with the bowl and at the other end by a chambered enlargement to receive the mouthpiece and a receptacle removably connected to the stem adjacent to the bowl into which receptacle the ducts of the stem deliver, said removable receptacle being so located as to expose the ends of each of the two ducts in the stem when it is removed.

2. A tobacco pipe having a stem at an acute angle to the bowl said stem having upper and lower ducts parallel to its axis which ducts are connected together at the lower end by one from the bowl and at the upper end by a chambered enlargement to receive the mouthpiece, and a receptacle removably connected to the-lower end of the stem, said removable receptacle being so located as to expose the ends of each or the two ducts in the stem when it is removed.

3. A tobacco pipe the stem of which has a bushing which adjacent to the bowl projects beyond the end of the stem and is threaded to hold a receptacle and at the other end terminates within the stem to provide a socket for the mouthpiece, said stem having an upper and lower duct parallel to the axis oi the stem and a straight duct connecting both with the bottom of the bowl, and a receptacle fitting-onto the thread of the bushing end, said removable receptacle being so located as to expose the ends of each of the two ducts in the stem when it is removed.

4. A tobacco pipe having a stem at an acute angle to the bowl beyond the axis of which it projects at the lower end, said stem having upper and lower ducts parallel to its axis and a duct in approximate alinement with the axis of the bowl intersecting both ducts of the stem, a removable receptacle on the lower end of the stem into which receptacle the lower ends of all the ducts deliver, and a mouthpiece removably attached to the end of the stem the duct of which is chambered to connect both ducts of the stem, said removable receptacle being so located as to expose the ends of each of the two ducts in the stem when it is removed.

5. A tobacco pipe comprising a bowl having a stem extending at an acute angle to the axis of the bowl and having an axial bore of uniform diameter from end to end, a mouthpiece having a nipple to enter said bore at its upper end, said mouthpiece having a bore provided with an enlargement at its shank end, a bushing held within said stem bore,

said bushing having a pair of parallel longitudinal ducts extending from end to end, said ducts at the upper end communicating with the enlarged end of thebore of said mouth piece, said bushing project-ing below said shank or stem, a receptacle fitted on said projecting end of said bushing, said bowl and said bushing having a bore extending in the direction of the axis of the bowl and communicating with both of said bushing longitudinal bores and with said receptacle, said removable receptacle being so located as to expose the ends of each of the two ducts in the stem when it is removed sub stantially as shown and for the purposes described.

6. A tobacco pipe comprising a bowl having a stem or shank extending at an acute angle to the vertical axis of the bowl, said stem having an axial bore of uniform diameter from end to end, a mouth-piece having a nipple projected into said bore at the upper end of the same, said mouth-piece having a duct extending from end to end and enlarged at the nipple end, a bushing of uniform external diameter from end to end held within said stein bore, said bushing having two parallel longitudinal bores extending from end to end, the lower of said bores being of greater cross sectional area than the upper one of said bores, and each of said bores at one end communicating with the enlargement of said mouth-piece bore, said bushing projecting downwardly beyond said stem, a receptacle secured on the projecting end of said bushing and with which the adjacent ends of said bushing bores directly communicate, said bowl and said bushing having a bore extending in the direction of the axis of said bowl and intercepting the upper one of said bushing bores and communicating with the lower one of said bushing bores and directly with said bowl, substantially as shown and for the purposes described.

In testimony whereof I aflix my signature in presence of two witnesses.
